When a 16-year-old attacked his former school in Schongau on 8 July, the 19-page manifesto made headlines. What didn't: 135 posts he left on an incel forum. The account is gone now, but we archived it first. (CW: extremism, misogyny, violence) 1/7

On 31 July 2026 a Munich court ruled that Suno had trained its music AI on protected songs like "Atemlos durch die Nacht" without a licence, storing them in the model. Our ECIS 2026 short paper asks: what if you caught that before training? By @riekers.bsky.social & @risius.bsky.social 1/9

Looksmaxxing is often framed as self-improvement. But when does optimizing one’s appearance become a worldview that explains almost everything? Our colleague Christopher David discussed this in a recent #Tagesthemen segment on ARD, Germany’s largest public broadcaster. 1/5

In short: Not what we had expected. We find people's responses don't get more accurate but at least they search more thoroughly. So we keep working on this and update you as we go!

AI-powered “looksmaxxing” apps are increasingly appearing in mainstream platform environments. Marketed as self-improvement tools, they promise facial ratings, attractiveness scores and advice on how to “optimise” appearance. 1/5

In this line of research we consider trust & safety issues from a broader information warfare (IW) perspective. Turns out, the term IW is used quite loosly ... and now we start talking about other types of warfare. In this paper @afrenzel.bsky.social gives an overview over common IW practices

Ever wondered how Incels and RWEs gatekeep new members online? We did! We find two fundamentally different ways in which members socialize in these extremist communities. Intriguing work by @cvdavid.bsky.social!

I know there is a vivid debate around how to operationalize hate speech. Not sure I agree with TT-US' understanding of what constitutes hateful content: zeteo.com/p/trump-tikt...

What is the gossip on why X is releasing new content moderation features? Seems off-brand to me. What am I missing? www.techspot.com/news/110332-...

X wants to call you out for using a VPN (and maybe catch a few trolls, too)
The situation began in October when Mikita Bier, X's Head of Product, announced that new information would be shown on user profiles, such as the date they...

@riekers.bsky.social is doing awesome work using multi-agent systems, in this case to detect hate speech in memes. Quite a challenging task but a promising approach and much more to come. Reach out if you're interested or struggling to find explainable AI solutions for multimodal applications

While prebunking has mostly been used in the disinformation context, @marcoduerr.bsky.social explores its potential for dealing with other kinds of harm - in this case authoritarian attitudes. While these preliminary results are promising, we work to further refine these interventions.

Published 2025 but maybe already outdated? The rapid advance of AI and the fundamental shifts to our (increasingly hyperpersonalized) information environment, we might have to revisit this sooner than expected.
